How to do new-style lazy formatting python logging

This concerns pylint and python logging. The following code doesn't work:

logging.basicConfig(level=logging.DEBUG, format='{message}', style='{')  log.debug('url {}', url)  

It raises:

  File "/usr/lib/python3.9/logging/__init__.py", line 363, in getMessage      msg = msg % self.args  TypeError: not all arguments converted during string formatting  

How do I make the logging work with the {} style instead of %s?

I'm using this basicConfig while testing my modules but I can also have a more advanced formatter in my package. The reason I started exploring this is because pylint was complaining when I used f-strings, but also when I was using old formatting with (%s).
